黑洞社区 has launched a salary checking service on its jobs website.

The Salary Checker at www. enables job seekers to compare the salaries of more than 80 types of construction job.

The checker is based on a real-time database of thousands of jobs. Salaries can be broken down by UK regions or by international job markets such as America and the Middle East.

Users can compare salaries over the last three, six and 12 months, and check regional salaries by comparing them with national averages.

The building4jobs site also has a searchable database of institutions and a graduate section.
